Hi,
Could you add a setting to select a default model for new chats on macOS application? Currently, the selection is dynamic, and sometimes without notice, a new chat switches from ChatGPT-4o to ChatGPT-1o preview. This is frustrating when I want to use ChatGPT-4o but end up on the ChatGPT-1o preview model (o1-preview) instead. The design is inconvenient, especially for ChatGPT Plus users, as the preview model has a weekly limit of only 50 messages, which gets used up quickly.
